WATER- FILTER.

SPECIFICATION forming part of Letters Patent No. 652,927, dated J' u1y3, 1900.

Application filed November 7, 1899. Serial No. 736,161. (No model.)

To @ZZ whom it may concern.-

Be it known that I, ANDREW G. SHEAK, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented a new and useful Water-Filter, of which the following is a specification.

The invention relates to improvements in water-filters.

The object ofL the present invention is to improve the construction of waterfilters, more especially that shown and described in an application filed by me on or about September 6, 1898, Serial No. 690,278, and to simplify the same and lessen the cost of the construction thereof.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a vertical sectional view of a water-filter constructed in accordance with this invention. Fig. 2 is a horizontal sectional view on line 2 2 of Fig. l. Fig. 3 is a detail perspective view of the frame which supports the inner filtering-casing. Fig. 4 is a similar view of one of the sections of the top of the outer easing. Fig. 5 is a sectional detail of the removable guide for the cleaning device.- l

4Likenumerals of reference designate corresponding parts in` all the figures of the drawings.

1 designates an outer cylindrical casing provided at its upper end, which is enlarged, with exterior screw-threads 2, which are engaged by corresponding interior screw-threads of a depending annular flange 3 of an upper section or'cover 4 of the top of the casing, said top being hollow and bearing against a shoulder or seat 6, formed by the enlargement of the casing, similar to the construction described in the said application. Instead of constructing the top ofthe casing in one piece, as illustrated in the said application, it is lconnposed of a cover 4 and a lower separate section 5, fitting against the interior of the enlarged upper end of the casing and coperating with the cover or upper section 4 to form an interior compartment, and a suitable packing 2a is interposed between the sections at the upper edges of the outer casing.

The top of the casing, which is hollow7 to form the interior chamber 7, is provided at the center of its upper section or cover with anpopening 8, interiorly threaded and adapted to screw on a water-pipe. The bottom or lower section 5 is inwardly offset and is provided at its center with a socket 9, forming a ing-frame 11. The inwardly or upwardly Oifset lower section 5 forms a lower recess, in which is arranged a water-wheel 12 and which is substantially circular. The walls of the recess consist of a series of tapering portions 13, forming radially-arranged shoulders and provided with openings or passages 14, extending from the interior chamber 7 and having their lower terminals arranged to eject water horizontally. The curved faces 15 exdirect the water discharged from the openings 14 against the water-wheel, whereby the latter will be rotated. vThe streams of water ejected from the passages or openings 14 are delivered upon the water-wheel in a direction substantially tangential with relation to the same and to the casing, and as they are arranged at intervals, as illustrated in Fig.v 4 of the accompanying drawings, a positive rotation of the water-wheel is effected.

From the center of the bottom 16 depends a tube 17, and around the opening at the upper end thereof is a socket 18, forming a race for a series of antifriction-balls 19, upon which rests and revolves the frame 11, that carries a filtering-casing 20 of ,cylindrical form. The outer casing is provided at its bottom with an opening 21, adapted to receive a plug or a faucet and designed, to enable the water to ow through it for a purpose hereinafter described.

At one side of the casing are, arranged upper and lower substantially U -shaped guides, extending over the top and under the bottom of the inner filtering-casing and receiving a the exterior of the inner iltering-casing when the latter is rotated by the means hereinafter described. The cleaning device is preferably bearing for a shaft or journal 10 of a supportl tend gradually inwardly and are adapted to cleaning device 22, which is adapted to scour IOO in the forni of a stick of emery or natural I stone,and its ends are arranged in said guides.

The lower guide 23 may be secured to the outer casing in any suitable manner; but it is preferably fixed to the same to mount it permanently in position. The upper guide 24 is designed to be removable to facilitate the assembling and the separation of the parts, especially the introduction and removal of the inner filtering-cylinder, and for this purpose it is provided with a dovetailed inner portion which is interlocked with a dovetailed groove or recess 25 of the outer casing, as clearly illustrated in Fig. 5 of the accompanying drawings. The cleaning device is held against the lexterior of the inner filteringcasing by upper and lower springs 27, secured to the cleaning device and interposed between the same and the outer casing, and the construction of the `guides is such that the cleaning device is advanced and supported in p0- sition as the inner casing is worn away. The bottom of the outer easing is also provided` with a threaded opening located directly beneath the upper and lower horizontal guides, and this opening, which receives a removable plug 28, provides for the introduction and removal of the cleaning device and enables a new one to be readily supplied when necessary. The plug 2S is provided with a head forming a seat for a suitable packing, which provides a water-tight connection.

The inner filtering-casing, which may be of any desired form and which may be constructed of any suitable material, preferably consists of a cylindrical stone having a central longitudinal bore or opening 29, through which passes a shaft or spindle 30 of the supporting-frame 1l. The supporting-frame ll is composed of the said shaft or spindle 30 and upper and lower disks or plates 3l and 32, which engage the upper and lower ends of the inner filtering-casing, whereby the latter is securely mounted on the supportingframe. The lower plate or disk 32 is preferably formed integral with the shaft or spindle, which is enlarged at the upper and lower faces thereof at 33 and 34. The enlarged portion 34 is tapered and rests upon the antifriction-balls 19, and the upper enlarged portion 33 extends into the lower end of the bore or opening of the inner filtering-cylinder and closes the bottom of the latter. The shaft or spindle is of less diameter than the bore or opening of the inner filtering-cylinder to provide an interior compartment or chamber, and the upper disk or plate is provided with a depending annular fiange 35, forming a socket to receive the upper end of the shaft or spindle and fitting into the upper end of the bore or opening of the filteringcasing. The upper plate or disk closes the upper end of the filtering casing or cylinder and is provided with a central aperture through which passes a screw 36, which engages a threaded socket of the upper end 37 of the shaft or spindle. The screw is provided with an enlargement or head 38 and is adapted to force the upper and lower plates tightly against the ends of the filtering-casing, whereby water-tight connections are provided. The screw is provided with an extension which forms the journal l0 and which is threaded at 39 to engage the water-wheel, and the latter is constructed similar to that shown and described in the application before referred to. The water-wheel is provided with a threaded aperture and is screwed against the head 38, whereby it is rigidly connected with the supporting-frame 11.

The lower portion 40 of the shaft or spindle extends through the depending tube 17 of the outer casing, and it is provided with a longitudinal opening or bore 4l, which extends upward above the bottom of the interior compartment or chamber 29 of the filtering-casing, and it communicates with such compartment or chamber by transverse bores or openings, as clearlyillustrated in Fig. 1 of the accompanying drawings.

The bottom of the casing is provided with a depending annular fiange 43, arranged concentric with the depending tube and terminating short of the lower end of the same and forming an annular recess for the reception of a packing 44, and the said annular flange is interiorly threaded and is engaged by upper threads 45 of a nut 46. The nut, which has a tubular body portion, is provided with the upper screw-threads 45, and it has lower screw-threads 46, which are engaged by an interiorly-threaded end of a stop-cock 47, which controls the discharge of the filtered water. The nut is provided at an intermediate point with a handle portion 48, and its interior diameter is greater than the diameter of the lower portion of the shaft or spindle to provide a passage for water for a purpose hereinafter described.

The filtered water when the filter is in operation passes from the interior compartment or chamber of the filtering-cylinder to the stop-cock, and when it is desired to clean the filter the stop-cock is opened, the nut 4G is turned up to relieve the supporting-frame, and the plug of the opening 2l is removed to take the pressure from the interior of the filter and permit the water to escape at the exterior. The water is then ejected forcibly through the openings 14 of the top of the casing, and the water-wheel is caused to revolve rapidly. This causes the filtering cylinder or casing to rotate against the cleaning device, which, together with the flow of water, will rapidly and thoroughly clean the filter of all accumulations. The lower end of the nut 46 is normally seated against a packing 49, arranged on a shoulder formed by a fianged nut 50, which engages the threaded lower end 5l of the shaft or spindle. The flange is arranged at the upper face of the nut and forms a continuation of the same, as clearly illustrated in Fig. l of the accompanying drawings.

By raising the lower end of the nut 46 from the packing and the fianged nut an opening ICO IIO

is provided at that point and water is.. permitted to iiow through the depending tube of the casing l. After the filter has been cleaned the nut 46 is screwed tightly against the packing 49, which prevents any water from the exterior of the inner filtering-casing from passing through the bearing to the stop-cock. The packing 44 is preferably constructed of elastic material and is designed to be compressed sufficiently to permit the lower end of the nut to be lifted off of the packing 49, and when the nut is in engagement with the latter the packing 44 is also in engagement with its upper end.

What is claimed isv l. A filter comprising an exterior casing, a top composed of two separate sections, the upper section forming a cover and engaging over the upper edge of the exterior casing, and the lower section fitting within the exterior casing, an interior rotary filtering-casing, a water-wheel connected with the inner casing, and a stationary cleaning device, substantially as described.
